Glory to the Pokemon fliers- I am second only to their successor (not by any other name).
Can fly, is second and has two in his name (successor of Mew).
The first was replaced by a new model, the second went down in glory. The third will be me.
Few possibilites here. If first is mew, second is mewtwo and third is mewtwo post-memory wipe (either the one of his or everyone elses). Could also refer to robotic mew that was destroyed.
I lord over those of the sea, but I cannot speak as they do.
Is powerful enough to rule over other pokemon & possesses an ability that can sap their powers. Also communicates (speaks) using telepathy.
You all loved her more than me.
The weakest match... Might refer to mew again for being pink and lovable.It could also be dr. Fujis now deceased daughter amber (clone) whose death distressed mewtwo greatly (and led to his memory being wiped).
